[AC-2121] iOS: Tabbed Application changes orientation to Landscape/Blinking with an explicit orientation fixed to PORTRAIT

Every Tabbed Application, the same created by Project Wizard with Tabbed Application Template, with only 2 line added in file _Resources/ui/common/ApplicationTabGroup.js_ introduce a Layout probelem

function ApplicationTabGroup(Window) {
function ApplicationTabGroup(Window) {
	//create module instance
	var self = Ti.UI.createTabGroup();
	
	//create app tabs
	var win1 = new Window(L('home')),
		win2 = new Window(L('settings'));
	
	// HERE MY CHANGES
	win1.orientationModes = [Ti.UI.PORTRAIT,Ti.UI.UPSIDE_PORTRAIT];
	win2.orientationModes = [Ti.UI.PORTRAIT,Ti.UI.UPSIDE_PORTRAIT, Ti.UI.LANDSCAPE_LEFT, Ti.UI.LANDSCAPE_RIGHT];

	var tab1 = Ti.UI.createTab({
		title: L('home'),
		icon: '/images/KS_nav_ui.png',
		window: win1
	});
	win1.containingTab = tab1;
...

I've fixed the tab1 to only Ti.UI.PORTRAIT, Ti.UI.UPSIDE_PORTRAIT. I've fixed tha tab2 to Ti.UI.PORTRAIT,Ti.UI.UPSIDE_PORTRAIT, Ti.UI.LANDSCAPE_LEFT and Ti.UI.LANDSCAPE_RIGHT Launching this project with iOS 4.3, device iPhone 4 and SDK 2.1.3GA (but seems to be every 2.x affeccted) there are 2 bug managing the orientation properties of the tabs Example 1:

Launching Project in Portrait Mode

Switching between tab1 to tab2

Changing orientation to Lanscape, the tab2 layout will be in LANDSCAPE

Returning to tab1 the layout still persist in LANSCAPE

Example 2:

Launching Project in Portrait Mode

Switching between tab1 to tab2

Returning to tab1

Changing orientation to Lanscape, the tab1 layout will BLINK and seems to rotate between LANDSCAPE to PORTRAIT

These situation seems to be something wrong in the mapping of TAB orientation properties.
